NONSINKABLE AEROPLANE BODY I Fil ly 1' 1928 s Sheets-Sheet a Patented June 9, 1931 PATENT OFFICE LOUIS NYCZ, OFBINGHAMTON, NEW YORK NoNsmmLE AEROPLAJN'E BODY Application filed July 17,

My invention pertains to nonsinkable vessels and particularly tononsinkable aeroplane bodies, whereby it is provided that when an aeroplane body, by accident or other cause, lands upon the surface of the water, means are provided to keep the body afloat for a longer or shorter time.

' With these objects in view, my invention consists of the following 'novel features of construction and arrangements of parts as are more particularly hereinafter described and pointed out in the claims, reference being had to the accompanying drawings, in which:

Fig. 1 is a side view of my device in 'perl5 spective view.

The same reference characters denote like 30 parts in each of the several figures of the drawings. y p I In carrying out my invention I have the aeroplane body A, and having mountedthereon the wing B and having also the usual propeller and mounted within the body A I have the cabin structure D. I As a further part of my invention I have constructed within the side wallsof the aeroview of a detailed part of o plane body A the hinged sections C. C.

These sections are composedof an outer shell 2. 2 and mounted within the shell 2 I have an inner packing of cork 3. 3, conforming to the extent and outline of the outer surface 2, as 4 shown in Fig. 2 This section C so construct- 1928. Serial No. 293,377.

ed is hinged to the main body of the aeroplane by the hinges 4. 4.

As a further part of my device, I have horizontally mounted a shaft 5, on which is mounted a drum or disk body 6, and mounted over the disk body 6, I have the winding chain 7 and 7, the outer ends of the chain 7 and 7 are connected in any convenient man.- ner with the inner side of the filled hinged section C, at the point 8 and 8. These sections are formed two on each side of the aeroplane body A, spaced apart so as to form on each side of the aeroplane body A, the two hinged sections 0 and C, as shown in Fig. 3, of the drawings. Also I have the front shaft 5 and the rear shaft 5, on said aeroplane body A as shown in Fig. 3. In a modified form of my device, as shown in Fig. 4, I have mounted on shaft 5 and 5, at the inner ends of the same, a gear 9 and 9, and as a further part of my device, in the modified form, I have at the inner edge the sections C and C, a shaft 10, to which the sections C and C are hinged; On shaft 10 I have mounted the gear 9. 9, which may be slidably mounted upon the shaft 10; also mounted on the inner end of the shaft 10, I have the clutch 11, pivotally mounted to engage the gears 9. 9; also as a further part of my device, I have the pivoted levers 12, 12, pivoted on the pivot 13. 13, and from the outer 7 end of the pivoted levers 12. 12, pivoted on the shaft 13, 13, I have pivotally connected the curved lever 15, with the foot rest 16 thereon, and pivoted on the pivot 17. The inner end of the pivoted lever 15, has pivotal connection at 18 with the inner levers 12. 12 the outer ends of the curved levers 14. 14 have pivotal connection with the clutch 11 at the point 19, and engaging said clutch at that point. I

In the operation of the first form of my device, as shown in Figs. 1 and 2, when for any reason the aeroplane body A is about to enter on. Water, by operating the pulleys 6, 6, the

chains 7. 7 connected with the hinged sections C, draw the hinged sections outward horizontally so as to form a corked horizontal surface to sustain and support upon the water surface the body of the aeroplane A. Also in the modified form of my device, as shownin Figs. 4, and Figs. 5, when the body of the aeroplane is about to enter the water, by pressing upon the foot rest 16, the pivoted lovers 12. 12, which in turn move the sliding clutch 11, causing the gear 9 to be brought in connection with the gear 9. 9, causing gears 9. 9 to revolve and thereby turning shafts 10. 10 and thereby turning the sections C and G into an outward horizontal hinged position, the same as is accomplished by the chains 7 and 7, shown in Fig. 2 and thus forming a horizontal nonsinkable floating surface projecting from the aeroplane I body A, and to prevent the same from sink- As a further part of my device, and a modified form of the same, I have the structure, as shown in Figs. 6 and 7, and in this aeroplane body A, and mounted thereon, I have horizontally pivoted, front and rear sections E. E, and the horizontally mounted sections E. E; and as a further part of the structure I have mounted within the aeroplane body A, in any convenient manner the vertical shafts 20. 20, and on the outer surfaces of which I have mounted the coil spring structure 21 21, surrounding the shafts, and at the upper end of which shafts the springs engage a head structure 22. 22, mounted on shaft 20', 20. And also mounted in connection with it I have the pulleys 24. These pivoted heads 22. 22, have engagement with the inner portion or ends of the horizontally mounted planes E. E, and E. E. Recessed in the heads 22. 22, I have the openings 23. 23,'adapted to receive a turn handle or turn bar, and in connection with it I have a pawl and ratchet construction for holding in a coiled position'the springs 21. 21, and operating the turn heads 22. 22 and with it the pivotal wings E. E, and E. E, respectively. In the operation, the pulleys 24. 24, being wound up by a turn bar or other means, and the aeroplane body A drops to the water, from any cause, then by releasing the spring turned heads 22. 22,

- it causes them to revolve, and operates the pulley 24 and belt connection 25, mounted thereon, connected with the pulleys on the under side of the pivotal planesE. E, and

E. E, and causes them to turn outward in horizontal alinement, to position shown in Fig. 7, and thus causing to be placed upon the water surface parallel extended floats filled with nonsinkable substance, thereby causing the body A to float and having a tendency to support and sustain the body to float upon the water surface.

As a further part of my device, I have the shaft 20 on which is mounted the ratchet 26,

also I have mounted on a standard a, the shaft 27, and pulley thereon 28; also on shaft 20 I have the crank arm 29, also mountedon shaft 27, I have a hand lever 30 on which is mounted the spring pawl 31, which contacts with a ratchet 32; also mounted on shaft 27 between pulley 28 and crankarm 29, I have a rod or cable 5.

As a further part of my device, I have mounted on shaft 20 the ratchet 33, and also at any convenient point I have mounted the pawl 34 to engage ratchet'33; also lOunted in any convenient position I have the vertical spring lever 35, pivoted on pivot 37 and having. connected therewith the coil spring 36, between this lever 35 and pawl 34, and connecting with lever 35, and pawl 34, I have the trip rod 38.

In the operation of my device the coil spring2l, mounted on the shafts 20. 2 0, is wound up and tensioned by the operation of the lever and pawl 30 turning the pulley 28 and the rod or cable I and thereby turning the crank arm 29, and ratchet 33 on shaft 20. The ratchet is held in tension-by the spring pawl 34, connected therewith as the winding proceeds, until by the turning of the shaft 20, the wings E. E, and E. E, are

drawn'pivotally into placein horizontal pos1t 1onon the'top of the body A, as shown in Fig. 7. The wings are again released and unwound at'any given time by operating the lever 35 and triprod 38 andreleasing' awl 34 from contact with the ratchet 33, an, the shafts 2Q. 20 again revolve and with them pulleys 24. 24, and connecting chains25. 25, ghicllinout-turn the pivoted wings E. E, and Having thus described my invention, what I claim as new and for which I desire Letters Patent is as follows 1. In an aeroplane body, hollow adjacent, parallel, pivotally mounted sections on top of the aeroplane body, filled with nonsinkable substance, pivotal spring operated supports beneath and at the ends of the same, means for contracting said spring mounting for drawing said sections into pivotal horizontal alinement, and means for releasing said springs andv projecting said, wings into parallel outward alinement at right angles to the side of the aeroplane body,

2.1In an aeroplane body, opposing fQlB and aft side sections pivotally secured to said body adjacent the upper surface thereof, each section being hollowand filled with non- .sinkable 'material, and, normally disposed against the body when in'inoperative'positron, and operating means for moving sa d sections away from th'e body into substantial filled with buoyant material, pivotal spring operated supports beneath said sections and disposed at the ends of same, means for tensioning said spring mounting for drawing said sections into pivotal, horizontal alignment, releasing means for said springs whereby said seotions are projected outwardly into parallel relationship at right angles to the side of the airplane body and means for retracting said sections into inoperative position.

In testimony whereof I have aflixed my signature.
